Even though I had braces as a kid (middle school age) and am not up on the lingo, so please forgive my odd descriptions for things I don't know/remember the name of!
Right now I have four elastic spacers (Jan.

I went thinking maybe clear braces (um...the invisalign type) for a few months for the bottom ones. I really didn't consider the tmj could be helped via braces. And the clear type were still a viable option, but I would still have tmj issues. I am a heavy teeth grinder and due to this my bite slips around at night and has shaved quite a bit off my upper incisors. The orthodontist said that he had just seen a lady in her 60's who had suffered for decades with similar issues and who had figured (like me) that nothing could be done. So, figuring that I have enough pain and headaches in my life (I have crohn's and migraines) I thought I should do whatever I can to minimize that. I also had a filling fail and had my first root canal last year. He said the overextruded molars and the pressure exerted on them was probably a contributing factor to the tooth's failure. I've had constant pain and sensitivity on that whole side ever since.
So...I went from thinking I would have clear trays for maybe six months to full braces for a year-ish, with a TAD screwed into my palate and a device wired up with coil springs to intrude those silly molars. A part of me can't believe I'm getting braces..again! After the first time, we moved out of state, I lost my retainers and my parents never had a care for it again. Sigh.
I'm getting molds and computerized images made next week (Jan. 21) for this fancy-shmancy robot that bends the wires to precise specifications to reduce the time it takes to move those suckers. (Is that a normal thing?? Idk, I'm about 15 years out of date with this stuff.)
Then I don't get braced until Feb.12 (happy valentine's day to me). Ugh, so loooong! And I'm not sure if I have to have these stupid spacers in the whole time. Yuck. It's not been funhttp://www.archwired.com/phpbb2/posting.php?mode=post&f=9#. Sometimes I just want to rip them out. If I read one more story about ppl having their spacers on for only a week or two I'll screamhttp://www.archwired.com/phpbb2/posting.php?mode=post&f=9#. jk, sort of.
Well, that's the gist so far. I'm feeling mighty impatient for this whole shebang to start already. Can't believe I have to wait till February, argh!
